To be honest, after meeting this metal egg, Gawain finally realized how lucky his present circumstances had been: he hadn't lost his memories; he landed in a world that was similarly dominated by humans; he even had an identity that allowed him to smoothly integrate into the current world (though this identity consisted of some scary and occult elements to some extent) and a satellite vision that might come in very handy. Most importantly, he possessed the memories of Gawain Cecil.
